Application filed may 3, 1913. Serial No. 765,212.

To all whom it may concern Be it known that we, lfinaxluan A. RJ-IEUE, acitizen of the United States, residing at Manchester, county 01 Essex,St te of Massachusetts, and Jonn Kinwioz, a citizen of the UnitedStates, residing at Boston, county of Suffolk, State of Massachusetts,have invented an Improvement in Sewing-Machines, of which the followingdescription, in connection with the accompanying drawing, is aspecification, lik'echaraeters on the drawing representing like parts.

'This invention relates to sewing machines and has for-one of itsobjects to ,provide a novel and simple mechanism for operating theshuttle whereby the number of parts is reduced r ad a construction isprovided which enables the machine to run at a high speed withoutvibration.

\Vhile our invention is applicable to various types of sewing machines,it is part-icularly applicable to machines of thatv type in which theneedle is sustained by a needle bar that operates in a horizontal planebeneath the bed frame of the machine, as is usually done in a socalledfinisher machine, and, therefore, we have illustrated the invention asit would be applied to a machine of this type.

In order to give a specific illustrationof the invention, we have chosento show it as it would be applied to a finisher machine of thetype shownin patent to Kiewicz, N 0. 1,047,537, dated December 17, 1912. We wishto state, however, that the invention is not limited to use in thisparticular type of machine.

' Referring now to the drawings, Figure 1 is a side view of a finishingmachine such as shown in said Kiewicz Patent No. 1,047,537, with aportion broken out to illustrate thein'vention; Fig. 2 is an endview ofthe bed plate with a part broken out to illustrate the invention; Fig. 3is a section on the line a'--m, Fig. 2; Fig. 4 is an under side view ofthe machine.

"QWehave shown at 1 the bed plate of the machine beneath which isjournaled the usual driving shaft 2 by which the parts are driven, saidshaft being operated from a loose pulley 3 thereon by suitable clutchmechanism designated generally by 4 which ilt will not be necessary todescribe at all in etai l The needle 5 is secured to a needle bar 6which reciprocatesin a swinging frame 7 that is given its lateralmovement by means of the connection 8 operated from the switch cam 12 onthe main shaft 2, as'usual in mament for the operation of the stitchesby the switch cam 12.

Finishing machines of the above-described type have as a part thereofbenders for forming bends in the work, thus enabling blind. stitches tobe formed. The bender is shown at 13 andis mounted on a swinging arm 14which is illustrated as pivoted to the frame at 15 and is given itsvibrating movement by means of a cam on the main shaft 2, all asillustrated in said Patent No. 1,047,537.

300 is a resser-foot carried bya vibratin arm 31 also pivoted to theframe at'15, sai

arm having an extension 32 which cooperates with the clutch mechanism.in such a way that when the clutch is released the presser-foot iselevated. This feature is also illustrated and described in theaforesaid I patent.

Cooperating with the needle in the operation of forming the stitch is ashuttle, as usual in sewing machines of this type, said shuttle notbeing shown herein as it forms no part of our invention. This shuttle issustained by an oscillatory shuttle carrier which is mounted to turn ina block 18 secured beneath the bed plate and which is provided with adepending shaft or pin 19 carrying at its lower end an arm 48 providedwith a stud 47 playing in a slot 46 of an oscillatory member -14 whichis pivoted at 45.

The parts thus far described are or may be substantially as shown in theaforesaid patent, and as the operation will be readily understood, nofurther description thereof is deemed to be necessary 1 In our presentinvention we provide a simple and novel mechanism for operating theshuttle which consists of means for connecting the oscillatory member 44directly to the needle bar, so that the'reciprocations of the needle barare transmitted directly to the shuttle carrier and thus to the shuttle.We accomplish this end herein by providing the pin 11 to which theactuating link is secured with an extension QOand which'is received inan aperture in the end: 21 of a link or connecting member 22, the otherend of which is pivotally connected'to the oscillatory member d4, asshown at 23. The pin or projection 11 is provided with a guiding flange24, the upper edge of which is received in a groove 25 formed in the Iunder side of a guiding member 26 secured to: the bed plate, guidingflange 24 7 serving to maintain the pin 11, and conse- Lquently the endof the connecting member 10, in a right line. It will be rememberedthatthe needle bar has a lateral movement,

and this lateral movement is permitted by a sliding connection betweenthe block 130 and the pin IL The projection 20 is shown as provided witha head 30 which is receivcd bchindguiding lips-33 secured to the endwill-13s of the bed frame, said guiding lips acting in conjunction withthe guiding fiange ,2-1- and groove 25 1n holding the parts in a correctright line during their re cip rocatingg movement. With thisconstruction it will be noted that there is a direct and singleconnection between the pin ll by which the needlebar is actuated and theoscillatory member 44, this single connection comprising simply the link22. i The, shuttle is, therefore, directly operated from,

the needle-har-actuating mechanism and no separatedevlce or set ofdevices for actuat: ing the shuttle irom the main shaft 2 s required, asis illustrated in the before-mon tioned patent. This constructionreduces the number of parts in the machine materially and provides aconstruction which can be operated at high speed without anyinconvenience;

While, we have illustrated herein one embodiment of our invention, We donot wish tobe limited to the constructional features shown.

Having fully described our invention,

what we claim as new and desire to secure by Letters Patent 1s:

1. In a sew1ngmach1ne, the combination with a bed plate frame, of ahorizontallyreoiprocating needle-bar beneathzsaid bed plate, a pinextending laterally from th needle bar, means on the frame fr *ming a,guidejfor; the end of the pin,'actuatii mechanism connected to said pinfor aetutitmg the needle bar, a shuttle carrier, and

means connected to said pin for actuating the, shuttle carrier. ,1

2. In a sewing machine, the combination with a bed plate frame, of ahorizontally- -reciprocating needle-bar ben ath said bed plate, a pinextending latera ly from said needle-bar, guid ng means on the frame forrecelvmg and gu dingthe end of the pin, a

driving shaft, a connecting rod connecting Sflld shaft and pm, a shuttlecarrier, an oscillatory member connectedthereto, a link connecting saidoscillatory me1 nber to said pin, the latter havmga, gtudmg flangethereon betweenf said link and connecting rod, andthe bed frame having aguldlng groove to receive said flange.
